    entryArea: Enable type-ahead for shift-only key combos
    
    We need to filter out key events with modifiers for type-ahead, so
    that keyboard shortcuts don't unexpectedly move focus. However a
    shift-only key combo is generally not a shortcut, but an upper
    case letter, so do not filter those out.
